Access to the unsecured site at ionos

Hello,
my site is the ionos server with the SSL certificate activated, but still unable to access the site. The error displayed "The connection is not secure".
I uncommented the solutions one by one in the HTaccess at the root of the site but nothing to do.

I used this one by default but the other redirects don't work either

  RewriteCond %{HTTPS} off
  RewriteCond %{REQUEST_METHOD} !=POST
  RewriteCond %{REQUEST_URI} !^\.well-known/
  RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]```

Thank you for your help

The code you uncommented just forces an SSL connection (port 443).
You still have to install/configure a certificate for your domain name with your web host.
Contact Ionos for directions.

I reinstalled the site directly on my server and it's ok

Welcome aboard :)
